因此，我尝试按照 Signal 官方网站给出的说明在 Ubuntu 20.04 LTS 上安装 Signal-desktop：-
# NOTE: These instructions only work for 64 bit Debian-based
# Linux distributions such as Ubuntu, Mint etc.
# 1. Install our official public software signing key
wget -O- https://updates.signal.org/desktop/apt/keys.asc | gpg --dearmor > signal-desktop-
keyring.gpg
sudo mv signal-desktop-keyring.gpg /usr/share/keyrings/
# 2. Add our repository to your list of repositories
echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/signal-desktop-keyring.gpg]
https://updates.signal.org/desktop/apt xenial main' |\
sudo tee -a /etc/apt/sources.list.d/signal-xenial.list
# 3. Update your package database and install signal
sudo apt update && sudo apt install signal-desktop
当我跑第一圈的时候，我得到了
deep@maharajadhiraja-deep:~$ wget -O- https://updates.signal.org/desktop/apt/keys.asc | gpg
--dearmor > signal-desktop-keyring.gpg

因此我无法安装 Signal-desktop。此外，
sudo apt-get <function>
也不起作用。例如，当我尝试在终端上运行：
sudo apt-get upgrade
它返回：-
E: Conflicting values set for option Signed-By regarding source
https://updates.signal.org/desktop/apt/ xenial: /usr/share/keyrings/signal-desktop-
keyring.gpg !=
E: The list of sources could not be read.
E: Conflicting values set for option Signed-By regarding source
https://updates.signal.org/desktop/apt/ xenial: /usr/share/keyrings/signal-desktop-

我不知道这里发生了什么。请帮帮我。
我是 Ubuntu 的新用户，我正在尝试自己弄清楚。提前感谢您的关注。
答案1
这两个问题，即 signal-desktop 的安装和运行以及 apt-get 功能返回此错误，都来自 中的意外内容/etc/apt/sources.list.d/signal-xenial.list。（就我而言，这是在尝试安装 signal-desktop 的测试版时引入的）。
我只需删除有问题的 apt 文件：
sudo rm /etc/apt/sources.list.d/signal-xenial.list
之后，重新执行https://signal.org/de/download/#安装信号后一切就绪。
答案2
signal-desktop从 Ubuntu 软件中心安装。
它将是一个更加干净的安装，并附带它所需的所有附加部件。
